考察烧焦动力学行为,寻找适宜的再生条件,对再生反应器的设计是十分必要的。已有大量的文章论述了关于硅铝型及Y型分子筛催化剂上的结焦和烧焦过程的模型,由于烧焦方式与焦在催化剂酸位上的生成方式有关,因此上述众多的模型都不能直接用于描述T-81型丝光沸石的烧焦过程。本文以Hashimoto等人提出的烧焦是烧碳和烧氢的复合反应为理论基础,研究了T-81型丝光沸石催化剂的烧焦动力学,为确定最佳反应条件和再生反应器的设计提
Studying the kinetic behavior of scorching, looking for suitable regeneration conditions, is very necessary for the design of regenerative reactor. A large number of articles have discussed models of coking and charring processes on silica-alumina-type and Y-type molecular sieve catalysts. Since the scorching mode is related to the formation of coke on the acid sites of catalysts, none of the above mentioned models can be directly Used to describe the charring process of T-81 mordenite. In this paper, Hashimoto et al proposed scorching charring and burning hydrogen composite reaction as the theoretical basis of the T-81 mordenite catalyst scorching kinetics, in order to determine the optimal reaction conditions and the design of the regeneration reactor
